Abstract: A spectrometer includes a light source configured to emit a beam along a beam path through a sample volume comprising an analyte. Also included is at least one detector positioned to detect at least a portion of the beam emitted by the light source, and at least one reflector positioned along the beam path intermediate the light source and the at least one detector having a surface roughness greater than a predefined level such as 20 Å RMS.

Abstract: Background composition concentration data representative of an actual background composition of a sample gas can be used to model absorption spectroscopy measurement data obtained for a gas sample and to correct an analysis of the absorption spectroscopy data (e.g. for structural interference and collisional broadening) based on the modeling.
